Title (EN) SAND DECANTER
(FR) DÉCANTEUR DE SABLE
Abstract:
(EN) A method for processing hydrocarbons recovered from a subterranean formation is disclosed. The method includes: feeding a stream including water, sand, and heavy hydrocarbons produced from a subterranean formation to a separation vessel; concurrently in the separation vessel: heating the stream components to an elevated temperature to reduce a viscosity of the heavy hydrocarbons; and separating the sand, the heavy hydrocarbon, and the water to form a water fraction, a hydrocarbon fraction, and a sand fraction comprising sand and at least one of water and heavy hydrocarbons; and recovering the water fraction from the separation vessel; recovering the hydrocarbon fraction from the separation vessel; and withdrawing the sand fraction from the separation vessel. Also disclosed are apparatus suitable for performing the above described method.
(FR) La présente invention concerne un procédé de traitement d'hydrocarbures récupérés d'une formation souterraine, lequel consiste à introduire un courant comprenant de l'eau, du sable et des hydrocarbures lourds produits par la formation souterraine dans une cuve de séparation, chauffer simultanément les composants du courant dans ladite cuve à une température élevée pour réduire la viscosité des hydrocarbures lourds, séparer le sable, les hydrocarbures lourds et l'eau pour former une fraction aqueuse, une fraction d'hydrocarbures et une fraction de sable comprenant du sable et de l'eau et/ou des hydrocarbures lourds, récupérer la fraction aqueuse, récupérer la fraction d'hydrocarbures, et retirer la fraction de sable de la cuve de séparation. L'invention concerne également un appareil permettant de mettre en œuvre ledit procédé.
